The question is incomplete as it does not have the options which are:
I. only
I. and II. only
II. and III. only
I, II, and III.
Answer:
I, II, and III.
Explanation:
The mechanism of natural selection can be explained for the trait which is determined by one gene but the traits which can be determined by more than one gene like height (polygenic trait), the selection becomes very complex.
The natural selection can be explained by the phenotype produced in a population and that depends on the genes. The polygenic trait shows the variation in the population, therefore, it is impossible to predict only one mechanism and therefore all types of natural selection occurs on a population.
Thus, I, II, and III are correct.

Answer:
Urinary bladder - superior mesenteric ganglion
Explanation:
The inferior mesenteric ganglion is located in the center of the abdomen where the inferior mesenteric artery begins. The axons of postganglionic neurons extend through the hypogastric plexus. These neurons then innervate the blood vessels of several organs like the rectum, urinary bladder, and distal colon, etc.
The postganglionic neurons from superior mesenteric ganglion innervate the blood vessels of the small intestine and proximal colon.
